BACKGROUND

The field of the present disclosure relates generally to translucent projection systems and, more specifically, to projecting images and video onto translucent displays incorporated into baby-changing stations.

Many purchasers of aircraft and other fleet vehicles require that the vehicle be personalized for their brand or image. In many cases, this includes having logos or images on different surfaces of the vehicle. However, many of these customizations are expensive and would have to be removed if the vehicle is resold. These customizations also require special set-ups on the assembly lines, which then slows down the production process. Furthermore, these customizations would need to be implemented in areas with limited space for additional equipment. One particular area of customization is the lavatories of the vehicles, where the purchasers are looking for distinct features to increase their visibility and the comfort of their passengers. Accordingly, it would be advantageous to have a system that allows for customization of surfaces on vehicles without requiring changes to the production of the vehicle.

DETAILED DESCRIPTION

The implementations described herein relate to systems and methods for analyzing images and, more specifically, to translucent projection systems and, more specifically, to projecting images and video onto a translucent display incorporated into a baby-changing station constructed of one or more translucent materials. For the purposes of this discussion, a translucent material or display permits light to pass through, but diffuses the light so that objects on the opposite side are not clearly visible. In some examples, the translucent display is made from a material comprising an acrylic polymer and alumina trihydrate (ATH) similar to that of Conan®, created by E. I. duPont de Nemours and Company, Wilmington, Del., (DuPont) which is a solid material.

In particular, the translucent projection system includes a projector, such as a short-throw projector is controlled by a projector controller computer device. The projector controller computer device controls the projector as it transmits images to display on the translucent display. The projector projects the image on a projection face of the translucent display to be displayed through the translucent display on the display face of the translucent display. By projecting onto the projection face of the translucent display, there are no obstructions between the projector and the translucent display being projected onto. This prevents individuals from interposing between the projector and the display being projected onto, thus preventing shadows and other obstructions from obscuring the image. The projector is also hidden away from the viewer to increase the viewing experience. Furthermore, the projectors can be configured to display desired images, allowing for customization without requiring additional equipment. In addition the images can be changed when desired. The projectors can be configured to display images, series of images, videos, and/or animations.

In the case of a baby-changing station, the projector controller computer device is in communication with one or more sensors that inform the projector controller computer device if the baby-changing station is in an up or stowed position or if the baby-changing station is in the down or deployed position. The projector controller computer device instructs the projector to display an image when the baby-changing station is in the up or stowed position and to discontinue projection when the baby-changing station is in the down or deployed position. While a baby-changing station is used as an example implementation herein, after reading this specification it will be recognized other implementations and applications are within the scope of the present disclosure, including but not limited to other stowable support surfaces such as trays, tables, workstations, among others.

FIG. 1 illustrates a projector system 100 for projecting an image onto a translucent display 105 in accordance with the present disclosure. In the example, a translucent display 105 includes a translucent material that allows light to pass through, but is semi-transparent. For the purposes of this discussion, a translucent material or display permits light to pass through, but diffuses the light so that objects on the opposite side are not clearly visible. In some examples, translucent display 105 is made from a material comprising an acrylic polymer and alumina trihydrate (ATH) similar to that of Conan®, created by E. I. duPont de Nemours and Company, Wilmington, Del., (DuPont) which is a solid material.

In the example, translucent display 105 includes a display face 110 and a projection face 115, where the display face 110 faces a viewer (or observer) 120 and the projection face 115 faces one or more projectors 125. While the projector 125 shown in FIG. 1 is below the translucent display 105, the one or more projectors 125 can also be positioned above the translucent display 105, to any side of the translucent display 105, or even directly behind the translucent display 105. The one or more projectors 125 are configured to project images 130 onto the projection face 115 of translucent display 105. The image 130 is then viewed by the viewer 120 through the translucent display 105. In the example, the projector 125 projects the image 130 in reverse, so that it can be displayed in the proper orientation by the viewer 120. In the example, the projector 125 is at least one of a short-throw projector, an ultrashort-throw projector, a GOBO (goes before objects) projector, or other projector that works as described herein. The term GOBO (Go Before Optics) specifically refers to a device placed in “the gate” or at the “point of focus” between the light source and the lenses (or other optics). In the example, the projector 125 is only a short distance from the translucent display 105 and is configured to project on translucent display from that close distance. Furthermore, the projector 125 is configured to project onto curved or uneven surfaces, so that the image 130 does not appear distorted to the viewer 120. In this example, the projector 125 is programmed to adjust the image 130 that is projected to the contours and shape of the translucent display 105 that is being projected on to avoid skew. This adjustment can be made when the projector 125 is originally configured while being installed. In addition, the projector 125 is also configured to use keystone image correction techniques for where the projector 125 is at an angle to the projection face 115 of the translucent display 105.

The projector 125 is controlled by a projector controller 135. The projector controller 135 instructs the projector 125 as to which images 130 to project and when to project those images. The projector controller 135 can provide images to the projector 125. The projector controller 135 can also provide images that have been adjusted to the contours of the translucent display 105 to the projector 125. If the projector controller 135 determines that it is appropriate to go into a sleep mode, the projector controller 135 would then instruct the projector 125 to stop projecting images 130 to conserve energy, to reduce heat, and/or to reduce wear and tear on the projector 125. The projector controller 135 can activate sleep mode a predetermined period of time after a sensor signal has been received, after a series of images have been displayed a predetermined period of time, after a specific sensor signal has been received, or based on a command from one or more other computer devices. In some examples, the projector controller 135 is a part of the projector 125. In other examples, the projector controller 135 is separate from and in communication with the projector 125. In some further examples, the projector controller 135 controls multiple projectors 125.

FIG. 2 illustrates a block diagram of another projector system 200 for projecting an image onto a translucent display 105 in accordance with another example of the present disclosure. In projector system 200, translucent display 105 includes a display face 110 and a projection face 115. The display face 110 faces a viewer (or observer) 120. Projector system 200 also includes a plurality of projectors 125. Each of the plurality of projectors 125 are configured to project images 205 and 210 onto the projection face 115 of the translucent display 105. The projector controller 135 controls each of the projectors 125 to determine which part of the image 210 for each projector 125 to display based on the size and shape of the translucent display 105.

Furthermore, the projectors 125 are configured to project the image 210 to include an overlap area 215. The overlap area 215 combines the images 210 of the two projectors 125 to create a seamless image, so that there is no visible difference to the viewer 120 between the images 205. The projector controller 135 is programmed to control the plurality of projectors 125. The projector controller 135 instructs each projector 125 which image 205 and 210 to project and what to project in the overlap area 215. The projector controller 135 can use color matching and edge blending techniques to illuminate the overlap area 215 so that there is no visible difference to the viewer 120 between the image 205 and 210 and the overlap area 215.

FIG. 3 is a simplified block diagram of an example projector system 300 for executing the projector systems 100 and 200 (shown in FIGS. 1 and 2 ). In the example, the projector system 300 is used for controlling projectors 125. The projector system 300 is a projector controlling computer system that includes a projector controller computer device 310 (also known as a projector controller server) configured to project images onto surfaces. In some examples, the projector controller computer device 310 is programmed to control one or more projectors 125 based on data received from one or more sensors 305. In the example, projector controller computer device 310 is similar to projector controller 135 (shown in FIG. 1 ).

Projectors 125 are configured to project an image 130 onto the projection face 115 of a translucent display 105 so that the image 130 is displayed on the display face 110 of the translucent display 105 (all shown in FIG. 1 ).

In projector system 300, sensors 305 receive signals about the actions of a user. The sensors 305 can include, but are not limited to, faucet sensors, door lock sensors, flush button sensors, automatic paper towel dispenser sensor, motion sensors, infrared sensors, light sensors, and or any other sensor that allows the projector system 300 to operate as described herein. Sensors 305 connect to projector controller computer device 310 through various wired or wireless interfaces including without limitation a network, such as a local area network (LAN) or a wide area network (WAN), dial-in-connections, cable modems, Internet connection, wireless, and special high-speed Integrated Services Digital Network (ISDN) lines. Sensors 305 receive data about the activities of the user or system, and report those conditions to projector controller computer device 310. In other examples, sensors 305 are in communication with one or more client systems 325. In some examples, sensors 305 are in direct communication with one or more projectors 125, where the projectors 125 are directly activated based on the signals provided by the sensors 305. For example, a projector 125 can activate when a motion sensor detects movement.

In the example, client systems 325 are computers that include a web browser or a software application, which enables client systems 325 to communicate with projector controller computer device 310 using the Internet, a local area network (LAN), or a wide area network (WAN). In some examples, the client systems 325 are communicatively coupled to the Internet through many interfaces including, but not limited to, at least one of a network, such as the Internet, a LAN, a WAN, or an integrated services digital network (ISDN), a dial-up-connection, a digital subscriber line (DSL), a cellular phone connection, a satellite connection, and a cable modem. Client systems 325 can be any device capable of accessing a network, such as the Internet, including, but not limited to, a desktop computer, a laptop computer, a personal digital assistant (PDA), a cellular phone, a smartphone, a tablet, a phablet, or other web-based connectable equipment. In at least one example, one or more client systems 325 are associated with aircraft operation, such as for when to illuminate a return to seat image. In another example, the client system 325 provides real-time information, such as financial news to the projector controller computer device 310; so that the projector controller computer device 310 can instruct one or more projectors 125 to display the financial news on a translucent display 105.

A database server 315 is communicatively coupled to a database 320 that stores data. In one example, the database 320 is a database that includes a plurality of projector settings, a plurality of projection sequences, and additional information for projection. In some examples, the database 320 is stored remotely from the projector controller computer device 310. In some examples, the database 320 is decentralized. In the example, a person can access the database 320 via the client systems 325 by logging onto projector controller computer device 310.

FIGS. 4A and 4B illustrate a cross-sectional view of a sink-based projector system 400 in accordance with at least one example. FIGS. 4A and 4B illustrate a cross-sectional view of the sink-based projector system 400. The sink-based projector system 400 includes countertops 405, a sink area 410, and a splash back area 415. In the example, the sink-based projector system 400 also includes one or more projectors 125 configured to project images 425 onto one of more of the countertops 405, the sink area 410, and the splash back area 415.

In the example, the projectors 125 are configured to project their images when triggered by a triggering device 420, such as a faucet sensor. The triggering device 420 can include one or more sensors 305 (shown in FIG. 3 ), such that the sensors 305 report a current status of the triggering device 420 (aka on or off). In the sink-based projector system 400, the triggering device 420 is a faucet sensor that detects when a person places their hands near the sink area 410. The triggering device 420 then triggers water to be dispensed into the sink. The triggering device 420 transmits a signal to the projector controller 135 (shown in FIG. 1 ), which controls the projectors 125. The projector controller 135 instructs the projectors 125 to display one or more images 425. The projector controller 135 can also poll each triggering device 420 to determine a current state of the triggering device 420, such as actively dispensing water through the faucet.

FIG. 4C illustrates an overhead view 450 of operation of the sink-based projector system 400 (shown in FIGS. 4A and 4B). In this overhead view 450, an image 425 of swirling water, as an example, is being projected onto the sink area 410.

FIG. 5 illustrates a view 500 of a lavatory using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively). View 500 shows multiple display faces 110 of translucent display 105 (shown in FIG. 1 ) with projected images, including a countertop face 505, a sink area face 510, and a splash back area face 515. All three of these faces 505, 510, and 515 are displaying an image 130 (shown in FIG. 1 ) instructing the viewer 120 (shown in FIG. 1 ) to return to their seat, such as in an aircraft lavatory.

In other situations, other images 130 can be displayed on the faces 505, 510, and 515, such as, but not limited to, branding and logos, destination theming, trip progress information, news, emergency instructions, financial data (e.g., stock ticker information), video clips, and/or any other images or video desired. These images 130 can be displayed based on activation of a triggering device 420 (shown in FIG. 4 ), a control signal from projector controller 135 (shown in FIG. 1 ), and a signal from a client system 325 (shown in FIG. 3 ). In a first example, the projector controller 135 receives a signal from triggering device 420 that the triggering device 420 was activated. This signal causes the projector controller 135 to instruct one or more projectors 125 to project images 130 onto one or more faces 505, 510, and 515. In a second example, the projector controller 135 determines that a predetermined time period has been exceeded since the last signal from a sensor 305 or triggering device 420 and determine to instruct the projectors 125 to stop displaying image 130. In a third example, the projector controller 135 can receive a signal from a client system 325 instructing projector controller 135 to instruct the projectors 125 to display the return to seat image 130 on each face 505, 510, and 515.

FIG. 6 illustrates a view 600 of a lavatory using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively). In view 600, a projector 125 (shown in FIG. 1 ) is hidden in the wall behind a baby-changing station 605. The baby-changing station 605 is a translucent display 105 (shown in FIG. 1 ) and made of a translucent material. The projector 125 projects an image 610 on the surface of the baby-changing station 605 while the baby-changing station 605 is in the up or stowed position. In the example, the projector 125 stops projecting image 610 when the baby-changing station 605 is opened or in the down or deployed position. In other examples, the projector 125 is in baby-changing station 605 and the bottom surface of baby-changing station 605 is a translucent display 105. In some examples, the projector 125 begins projecting image 610 when a viewer 120 (shown in FIG. 1 ) is detected. For example, when the lock on the lavatory is put in the lock position and the lock includes a triggering device 420 (shown in FIG. 4A). The triggering device 420 transmits a signal to the projector controller 135 (shown in FIG. 1 ) to instruct the projectors 125 to display image 610 on the baby-changing station 605. The projector controller 135 can also receive a signal from a triggering device 420 associated with the baby-changing station 605 to determine whether the baby-changing station 605 is in an up or stowed position or a down or deployed position.

While a baby-changing station is used as an example implementation herein, after reading this specification it will be recognized other implementations and applications are within the scope of the present disclosure, including but not limited to other stowable support surfaces such as trays, tables, workstations, among others.

FIGS. 7A-7C illustrate an overhead view 700 of the baby-changing station 605 including a translucent display 105 (shown in FIG. 1 ) using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively). In FIG. 7A, view 700 includes a cut-away view of baby-changing station 605 in the stowed or up position. In FIG. 7B, view 725 displays the baby-changing station 605 in the deployed or down position. In FIG. 7C, view 730 displays the baby-changing station 605 in use. The baby-changing station 605 is configured to transition between a stowed position and a deployed position. The baby-changing station 605 includes hinges or other movement mechanics to allow it to transition between the stowed or up position and the deployed or down position.

As shown in view 700, the translucent projection area 720 includes a projection face 115 and a display face 110. The translucent material in the translucent projection area 720 is configured to allow images 130 to be projected onto the projection face 115 and be displayed on the display face 110.

A projector 125 is positioned in wall 705. The projector 125 can be a backlit short-throw projector 125. The projector 125 projects an image 130 through a lens 710 in the wall 705 onto the projection face 115 of the baby-changing station 605. The display face 110 of the baby-changing station 605 is the bottom side of the baby-changing station 605 when deployed or down. The projection face 115 of the baby-changing station 605 is the top side of the baby-changing station 605 when deployed or down.

The lens 710 can be a fish-eye lens or a wide-angle lens to allow the image 130 to be spread out to be displayed on a larger area. The lens 710 would be visible in the wall 705, when the baby-changing station 605 is deployed. The lens 710 can be protected by a shutter 712, such as a camera style shutter. The shutter could be a rotating, guillotine, diaphragm, iris, or other type of mechanism. The shutter 712 closes over the lens 710 when the baby-changing station 605 is deployed or in the down position. The lens 710 can also be protected by an optically transparent cover 714 either on its own or in conjunction with the shutter 712.

The baby-changing station 605, or at least a portion of the baby-changing station 605, is made up a translucent material, such as a material comprising an acrylic polymer and alumina trihydrate (ATH) similar to that of Conan®, created by E. I. duPont de Nemours and Company, Wilmington, Del., (DuPont) which is a solid material. The image 130 traverses through the portion of the baby-changing station 605 that it is projected onto and is displayed on the display face 110 of the baby-changing station 605. The image 130 is then able to be viewed on the display face 110 of the baby-changing station 605. The image 130 is projected in reverse onto the projection face 115 to display in the proper orientation on the display face 110.

As shown in view 700, the projector 125 is positioned perpendicularly to the translucent baby-changing station 605 to allow the image 130 to be transmitted clear and distortion free. The projector 125 can also be positioned at an angle to the translucent baby-changing station 605 and use keystone image correction to account for the angle. This includes moving the projector 125 and lens 710 along the wall to another position based on the available space requirements of the lavatory and/or the wall 705 containing the projector 125 and the lens 710. Furthermore, multiple static image projectors 125 can be used, where the projector controller 135 cycles images between the static image projectors 125 to display an animation or pseudo-animation.

Having the projector 125 positioned behind the wall 705 allows the projector an unobstructed path to project the image 130 onto the translucent baby-changing station 605.

The projector controller 135 instructs the projector 125 on which image 130 to display and when to display the image 130. The projector controller 135 is in communication with one or more sensors 305 (shown in FIG. 3 ) that inform the projector controller 135 which position the baby-changing station 605 is currently in. The sensor 305 can include, but is not limited to, proximity switch, magnetic switch, level switch, tilt/displacement switch, radial switch, mercury switch, latch sensor, and/or any other potential sensor 305 that informs the projector controller 135 of the current position of the baby-changing station 605. The projector controller 135 can disable projection as soon as it detects that the baby-changing station 605 no longer completely in the stowed position. This can prevent a user from having the projector 125 project light onto their face.

When the baby-changing station 605 is stowed, closed or up, the sensor 305 transmits signals to the projector controller 135 of the current position of the baby-changing station 605. The projector controller 135 can instruct the projector 125 to display one or more images, videos, and/or animations on the translucent display 105 of the baby-changing station 605. When the baby-changing station 605 is opened or deployed, the sensors 305 inform the projector controller 135 of the current position and the projector controller 135 instructs the projector 125 to discontinue projection of the image 130. When the sensors 305 inform the projector controller 135 that the baby-changing station 605 is closed or stowed again, the projector controller 135 instructs the projector 125 to resume projection of the image 130. In some examples, the projector 125 is in direct communication with the sensors 305 to know when to disable projection.

In a first example, the baby-changing station 605 includes a border area 715 and a translucent projection area 720. As shown in view 700 the border area 715 is thicker than the translucent projection area 720, where the translucent projection area 720 is recessed in relation to the surrounding border area 715. The border area 715 being positioned around the translucent projection area 720 provides an area to safely place and cradle a baby 735 to limit the possibility of the baby 735, and any other objects in the translucent projection area 720, such as changing supplies, from rolling off of the baby-changing station 605. The translucent projection area 720 is the area where the baby 735 is placed when the baby-changing station 605 is down or deployed.

In some examples, the translucent projection area 720 is made of a different material as the border area 715. In other examples, baby-changing station 605 can include a translucent material of a single thickness where the area to place the baby 735 is not recessed or where the area to place the baby 735 is molded to be recessed. The baby-changing station 605 can include one or more portions made of a translucent material that allows projections to pass through and include one or more portions made of a different opaque material.

The baby-changing station 605 can be manufactured out of a single translucent material. The baby-changing station 605 can also be manufactured from multiple different materials that are joined together, such as with a color matching adhesive. The translucent projection area 720 of the baby-changing station 605 can be created by thinning out a localized area via one or more of machining, chemical etching, thermal forming, molding, composite materials, and/or as an assembly of multiple parts.

The projector 125 can activate when the projector controller 135 (shown in FIG. 1 ) receives a signal from one or more triggering devices 420 (shown in FIG. 4A). For example, when the lavatory is not in use, the projector controller 135 puts the projector 125 into a low power mode. The projector controller 135 can do this after a predetermined period of time since any of the triggering devices 420 in the lavatory have been activated or after a predetermined period of time since one or more specific triggering devices 420 have been activated. For example, the projector controller 135 can instruct the projector 125 to go into a low power mode two minutes (120 seconds) after the door lock has been unlocked.

The projector 125 can go into multiple different power modes. The first power mode is normal power mode, where the projector 125 projects images 130 onto translucent displays 105 at full brightness (which can be a full brightness associated with the projector 125 or a full brightness preference set by a user). In a second power mode, the projector 125 does not project any images 130. In a third power mode, the projector 125 projects images 130 at a lower brightness, such as 25-50% brightness of full brightness. In one situation, the projector controller 135, for example, can put the projector 125 into the second low power mode after the door lock is unlocked and into the first low power mode after a predetermined period of time (aka two minutes). The projector controller 135 can instruct the projector 125 to transition from the first low power mode to the second low power mode when a triggering device 420 activates, such as the door of the lavatory opens. The projector controller 135 can then instruct the projector 125 to go into a normal projection mode when a signal is received from a sensor 305 indicating that the door is locked.

While the baby-changing station 605 shown in FIGS. 7A-7C is oriented in a horizontal orientation, the baby-changing station 605 can also be in a vertical orientation, such that when deployed the baby 735 would lie perpendicular to the wall 705 rather than parallel to the wall 705.

FIGS. 8A and 8B illustrate a side view 800 of the baby-changing station 605 including a translucent display 105 (shown in FIG. 1 ) using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively). In FIG. 8A, view 800 includes a cut-away view of baby-changing station 605 in the stowed or up position. In FIG. 8B, view 825 displays a zoom-in view of the baby-changing station 605 in the stowed or up position. View 800 includes a latch mechanism 805 for securing the baby-changing station 605 in the stowed or up position. The latch mechanism 805 can include one or more sensors 305 (shown in FIG. 3 ) to indicate the current status of the latch mechanism 805.

When the baby-changing station 605 is in the stowed or up position, the projector 125 transmits one or more images 130 through a lens 710 in the wall 705. The image 130 is projected onto a projection face 115 of the translucent projection area 720 of the baby-changing station 605. The image 130 is then displayed on the display face 110 of the translucent projection area 720 of the baby-changing station 605.

FIGS. 9A and 9B illustrate a side view 900 of the baby-changing station 605 including a translucent display 105 (shown in FIG. 1 ) using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively). In FIG. 9A, view 900 includes a cut-away view of baby-changing station 605 in the deployed or down position. In FIG. 9B, view 925 displays a zoom-in view of the baby-changing station 605 in the deployed or down position.

When the baby-changing station 605 is in the deployed or down position, the projector 125 does not transmit images 130 (not shown). The lens 710 is visible in the wall 705, but the projector 125 is out of view and reach of the user of the baby-changing station 605 as the projector is behind the wall 705.

FIG. 10A illustrates an overhead view 1000 of another configuration of a translucent display 105 (shown in FIG. 1 ) on a baby-changing station 605. FIG. 10B illustrates a side view 1025 of the other configuration of a translucent display 105 (shown in FIG. 1 ) on a baby-changing station 605.

Depending on the projector 125 used and/or the length of time that the projector 125 is in continuous use, the lens 710 can increase in temperature to a point where the lens 710 can harm an individual who touches it. Furthermore, in many situations the amount of space available for the lavatory is limited. Accordingly, it can be necessary to move or rearrange the configuration of parts of the translucent display 105 to address these issues.

As shown in views 1000 and 1025, the projector 125 is positioned parallel to the wall 705. The projector 125 projects the image 130 onto a mirror 1005, where the mirror 1005 is positioned on the projector side 1010 of the wall 705. The mirror 1005 is mounted using one or more fastening devices, such as brackets. The mirror 1005 is secured in a fixed position to prevent movement of the mirror 1005 and prevent the image 130 from becoming distorted. The mirror 1005 directs the image 130 through the lens 710 and onto the projection face 115 of the translucent projection area 720 of the baby-changing station 605, which is on the display side 1015 of the wall 705. While the mirror is shown at a 45 degree angle and the projector 125 is shown as parallel to the wall 705, both of these angles can change based on the required configuration. Furthermore, the projector 125 can be positioned above, below, or to the side of the lens 710 depending on the available space and required configuration.

FIG. 11 illustrates a view 1100 of a translucent display 105 (shown in FIG. 1 ) on a baby-changing station 605 using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively). View 1100 shows the display face 110 (shown in FIG. 1 ) of the translucent display 105 on the baby-changing station 605 in the stowed or up position. The display face 110 is displaying an image 130 (shown in FIG. 1 ) instructing the viewer 120 (shown in FIG. 1 ) to return to their seat, such as in an aircraft lavatory.

FIG. 12 illustrates a further view of a lavatory 1200 using the projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively). Lavatory 1200 includes a plurality of walls 705 and a floor 1210. Walls 705 and floor 1210 can include projector systems 300. Lavatory 1200 also includes a sink 1215 and a toilet 1220. The sink 1215 can be similar to sink area 410 (shown in FIG. 4 ). The toilet 1220 includes a toilet lid 1225, a toilet seat 1230, and a toilet shroud 1235. The toilet 1220 is associated with a toilet flush button 1240. The lavatory 1200 also includes a fold-down baby-changing station 605.

FIG. 13 illustrates a process 1300 for using the lavatory-based projector system in accordance with at least one example. In the example, process 1300 is implemented by at least one of a projector controller 135 (shown in FIG. 1 ) and a projector controller computer device 310 (shown in FIG. 3 ) programmed to control a lavatory 1200 (shown in FIG. 12 ) with a plurality of translucent displays 105 (shown in FIG. 1 ). In the example, the lavatory 1200 can have translucent displays 105 positioned in surfaces, such as, but not limited to, the countertops 405, the sink area 410, the splash back area 415 (all shown in FIG. 4A), the baby-changing station 605 (shown in FIG. 6 ), a wall 705 (shown in FIG. 12 ), or other surface, including but not limited to the toilet 1220, the toilet lid 1225, the toilet seat 1230, the toilet shroud 1235, the walls 705, the floor 1210 (all shown in FIG. 12 ), the ceiling, the cabinet faces, and any other visible surface in the lavatory 1200. While process 1300 describes the use of a projector system 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively) in a lavatory setting, the systems and methods described herein can also be used in vehicles, such as, but not limited to aircraft, watercraft, trains, buses, and spacecraft, and on other surfaces in the vehicle, such as, but not limited to, at passenger seats (e.g., tray tables), in galleys (e.g., work decks and sinks), passenger entryways (e.g., ceilings, floors, and walls), bar units (e.g., the countertops and fronts), and any other visible surface of the vehicle. Furthermore, these systems and methods would also be applicable to other environments, such as, but not limited to, bathrooms in homes and businesses (or hotels), kitchens, dining rooms, and other public areas of homes, businesses, or hotels. While a baby-changing station is used as an example implementation herein, after reading this specification it will be recognized other implementations and applications are within the scope of the present disclosure, including but not limited to other stowable support surfaces such as trays, tables, workstations, among others.

In process 1300, an occupant enters the lavatory 1200 and locks 1305 the door. The locking 1305 of the door triggers a first triggering device 420 (shown in FIG. 4A) which causes the projector controller 135 to activate 1310 a first projection sequence on specific translucent displays 105, such as, but not limited to, the wall 705, ceiling, floor 1210, baby-changing station 605, and cabinet faces. A projection sequence is an image, a plurality of images, and/or a video to be displayed on one or more translucent displays 105. As used herein, the first projection sequence, the second projection sequence, and the third projection sequence indicate differing sequences of images or video. Furthermore the different sequences can be projected on the same translucent displays 105 or different translucent displays 105. In some examples, the first projection sequence ends and continues to display an image, such as the last image of the first projection sequence. In other examples, the first projection sequence repeats until interrupted by a specific user action. The projector controller 135 receives a signal from the door lock that the door has been locked 1305, from a motion sensor, or any other sensor 305 (shown in FIG. 3 ) that indicates that projector controller 135 should activate the first display sequence and the projector controller 135 instructs one or more projectors 125 (shown in FIG. 1 ) to display the first projection sequence.

The user triggering 1315 the toilet flush button 1240 (shown in FIG. 12 ) activates 1320 the second projection sequence. The second projection sequence can be different from the first projection sequence in content of the projection sequence and/or location of the translucent displays 105 that the second projection sequence is displayed on. The second projection sequence can be displayed on one or more of the baby-changing station 605, the toilet 1220, the toilet lid 1225, the toilet seat 1230, and the toilet shroud 1235. The second projection sequence can be projected on the same surfaces as the first projection sequence. The second projection sequence can be activated 1320 after the toilet flush button 1240 is triggered 1315 and the toilet lid 1225 and/or the toilet seat 1230 is returned to the down position. The projector controller 135 receives a signal that the toilet flush button 1240 has been triggered 1315 and the projector controller 135 instructs one or more projectors 125 to display the second projection sequence. The flush sensor 305 can be separate from the toilet flush button 1240 and the flush sensor 305 detects when a flush occurs, such as in the case of an automatically flushing toilet. The second projection sequence can be displayed on any combination of the above listed transparent displays 105 in response to one or more of the triggers discussed above.

When the user triggers 1325 the faucet, such as by triggering 1325 the faucet sensor or triggering device 420 (shown in FIG. 4A), the third projection sequence is activated 1330. The third projection sequence can be displayed on one or more of the countertops 405, the sink area 410, and the splash back area 415. The third projection sequence can also be projected on the same surfaces as the at least one of the first projection sequence and the second projection sequence. The projector controller 135 receives a signal that the faucet sensor or triggering device 420 has been triggered 1325 and the projector controller 135 instructs one or more projectors 125 to display the third projection sequence. Similar to the second projection sequence, the third projection sequence can be displayed on any combination of the above listed transparent displays 105 in response to one or more of the triggers discussed above.

When the user triggers 1335 an automated paper towel dispenser, the fourth projection sequence is activated 1340. The fourth projection sequence can be displayed on one or more of the countertops 405, the sink area 410, and the splash back area 415. The fourth projection sequence can be projected on the same surfaces as the at least one of the first projection sequence, the second projection sequence, and the third projection sequence. The projector controller 135 receives a signal that the automated paper towel dispenser has been triggered 1335 and the projector controller 135 instructs one or more projectors 125 to display the fourth projection sequence. The fourth projection sequence can be displayed on any combination of the above listed transparent displays 105 in response to one or more of the triggers discussed above.

The different sequences can be triggered in a different order based on the user's actions. Furthermore, one or more of the sequences can be triggered based on additional sensors 305 present in the lavatory 1200, which can trigger other projection sequences.

The projector controller 135 can continue to display one or more sequences until the user disengages the door lock. The projector controller 135 can continue displaying one or more sequences for a predetermined period of time after the door is unlocked.

The projector controller 135 can also continuously display one or more images or video in a low-powered state, where the images are projected at a lower light level until the door lock is engaged.

The projector controller 135 can also interrupt any of the projection sequences to display an important message, such as the return to seat images in shown FIGS. 5 and 11 , or other pertinent information or indication, for example, provide visual indication that an occupant within the lavatory has pushed the attendant call button, the translucent display 105 might show an image/message that the attendant has been called.

FIG. 14 illustrates a process 1400 for using the lavatory-based projector system with a baby-changing station 605 (shown in FIG. 6 ) in accordance with at least one example. Process 1400 is implemented by at least one of a projector controller 135 (shown in FIG. 1 ) and a projector controller computer device 310 (shown in FIG. 3 ) programmed to control a lavatory 1200 (shown in FIG. 12 ) with a plurality of translucent displays 105 (shown in FIG. 1 ). The lavatory 1200 has a translucent displays 105 positioned in the baby-changing station 605. The lavatory 1200 can have translucent display 105 in other surfaces, such as, but not limited to, the countertops 405, the sink area 410, the splash back area 415 (all shown in FIG. 4A), a wall 705 (shown in FIG. 7 ), or other surface, including but not limited to the toilet 1220, the toilet lid 1225, the toilet seat 1230, the toilet shroud 1235, the walls 1205, the floor 1210 (all shown in FIG. 12 ), the ceiling, the cabinet faces, and any other visible surface in the lavatory 1200. While process 1400 describes the use of a projector system 100, 200, and 300 (shown in FIGS. 1, 2, and 3 , respectively) in a lavatory setting, the systems and methods described herein can also be used in vehicles, such as, but not limited to aircraft, watercraft, trains, buses, and spacecraft.

Process 1400 is a variation on process 1300 (shown in FIG. 13 ). In process 1300, an occupant enters the lavatory 1200 and locks 1305 the door. The locking 1305 of the door triggers a first triggering device 420 (shown in FIG. 4A) which causes the projector controller 135 to activate 1310 a first projection sequence on specific translucent displays 105, such as, but not limited to, the wall 705, ceiling, floor 1210, baby-changing station 605, and cabinet faces. A projection sequence is an image, a plurality of images, and/or a video to be displayed on one or more translucent displays 105. As used herein, the first projection sequence, the second projection sequence, and the third projection sequence indicate differing sequences of images or video. Furthermore the different sequences can be projected on the same translucent displays 105 or different translucent displays 105 The first projection sequence can end and continue to display an image, such as the last image of the first projection sequence. The first projection sequence can repeat until interrupted by a specific user action. The projector controller 135 receives a signal from the door lock that the door has been locked 1305, from a motion sensor, or any other sensor 305 (shown in FIG. 3 ) that indicates that projector controller 135 should activate the first display sequence and the projector controller 135 instructs one or more projectors 125 (shown in FIG. 1 ) to display the first projection sequence

In process 1400, an occupant enters the lavatory 1200 and locks 1405 the door. The locking 1405 of the door triggers a first triggering device 420 (shown in FIG. 4A) which causes the projector controller 135 to activate 1410 a first projection sequence on specific translucent displays 105, such as, but not limited to, the wall 705, ceiling, floor 1210, baby-changing station 605, and cabinet faces. A projection sequence is an image, a plurality of images, and/or a video to be displayed on one or more translucent displays 105. As used herein, the first projection sequence, the second projection sequence, and the third projection sequence indicate differing sequences of images or video. Furthermore the different sequences can be projected on the same translucent displays 105 or different translucent displays 105. The first projection sequence can end and continue to display an image, such as the last image of the first projection sequence. The first projection sequence can repeat until interrupted by a specific user action. The projector controller 135 receives a signal from the door lock that the door has been locked 1405, from a motion sensor, or any other sensor 305 (shown in FIG. 3 ) that indicates that projector controller 135 should activate the first display sequence and the projector controller 135 instructs one or more projectors 125 (shown in FIG. 1 ) to display the first projection sequence. The projector controller 135 can also interrupt any of the projection sequences to display an important message, such as the return to seat images in shown FIGS. 5 and 11 , or other pertinent information or indication, for example, provide visual indication that an occupant within the lavatory has pushed the attendant call button, the translucent display 105 might show an image/message that the attendant has been called.

The projector 125 associated with the baby-changing station 605 is currently projecting one or more images 130 onto the baby-changing station 605. The occupant deploys or lowers 1415 the baby-changing station 605. One or more sensors 305 associated with the baby-changing station 605 transmit 1420 to the projector controller 135 that the baby-changing station 605 is no longer fully in the stowed or up position. The projector controller 135 instructs the projector 125 associated with the baby-changing station 605 to stop projecting images. The projector controller 135 instructs the projector 125 to stop projecting as soon as it determines that the baby-changing station 605 is no longer fully in the stowed or up position, so that the projector 125 stops projecting before the baby-changing station 605 is fully in the down position. This timing reduces the likelihood that the projector will project into the eyes and/or face of the occupant. The sensors 305 associated with the baby-changing station 605 includes, but are not limited to, proximity switch, magnetic switch, level switch, tilt/displacement switch, radial switch, mercury switch, latch switch, or any other switch or sensor that indicates the current position of the baby-changing station 605.

While the baby-changing station 605 is in the deployed or down position, the occupant can place 1425 the baby on the baby-changing station 605 and caters to the needs of the baby. The occupant removes 1430 the baby from the baby-changing station 605 and closes or raises 1435 the baby-changing station 605 back to the stowed or up position. The sensors 305 associated with the baby-changing station 605 inform 1440 the projector controller 135 that the baby-changing station 605 is back in the stowed or up position.

The projector controller 135 instructs the projector 125 associated with the baby-changing station 605 to resume the projection sequence that it was projecting, such as the first projection sequence. The projector 125 can resume the projection sequence at the point that the sequence was stopped. The projector controller 135 can also synchronize the projector 125 associated with the baby-changing station 605 to be synchronized with the other translucent displays 105. For example, while the projector 125 associated with the baby-changing station 605 stopped projecting the first projection sequence; the other active projectors 125 in the lavatory 1200 continued projecting the first projection sequence. When the baby-changing station 605 is back in the stowed or up position, the projector controller 135 instructs the projector 125 associated with the baby-changing station 605 to start projecting the first projection sequence at the same point in the sequence that the other projectors 125 currently are.

When the projector controller 135 determines 1445 that the door has been unlocked, or that the movement has not been detected for a predetermined period of time, the projector controller 135 can instruct the projectors 125 to go into a sleep mode. When in the sleep mode the projectors 125 can stop the projecting images 130. When in the sleep mode, the projectors 125 can also continue to project images 130, but at a lower brightness (25-50% of full brightness).

FIG. 15 illustrates another process 1500 for using the lavatory-based projector system with a baby-changing station 605 (shown in FIG. 6 ) in accordance with at least one example. Process 1500 is implemented by at least one of a projector controller 135 (shown in FIG. 1 ) and a projector controller computer device 310 (shown in FIG. 3 ) programmed to control a lavatory 1200 (shown in FIG. 12 ) with a plurality of translucent displays 105 (shown in FIG. 1 ). The lavatory 1200 has a translucent displays 105 positioned in the baby-changing station 605.
